FILLING-REPLENISHING BATTERY OR MAGAZINE FOR LOOMS.

Application filed November 10, 1922.

To all whom it may concern:

Be it known that I, RANDoLrHCRoMrroN, a citizen of the United States, and a resident of lVorcester, in the county of Worcester and State of Massachusetts, have invented an Improvement in Filling-Replenishing Batteries or Magazines for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to filling replenishing batteries or magazines for looms.

In order that the principle of the invention may be readily understood, I have disclosed one embodiment of my invention in the accompanying drawing, wherein the figure is a vertical section taken through the battery or magazine of a loom.

Heretofore so far as I am aware, it has been necessary to apply lubricating oil to the rotating or movable parts of the batteries or magazines of looms, with the result that the oil has dropped upon or found its way to the filling carriers. The object of my invention is to overcome this difficulty and to provide a construction wholly avoiding the use of flowing oil as a lubricant and yet which will provide for the necessary lubrication.

Without limiting my invention strictly thereto, I will set forth the preferred embodiment of my invention.

My invention may be applied to many different types of looms and to many different types of batteries or magazines therefor. Herein I have represented a frame or case 1 of general disk form and which is adapted to be bolted or otherwise secured to the loom frame in a manner not necessary more fully to describe. Centrally secured to the disk 1 by a nut 2 is a stud 3 of suitable length carrying loosely thereon the sleeve 4 which itself is shown as having a gear 5 formed therewith. Rigid with the sleeve 4 are two disks 6, 7 of any suitable construction, and which receive the circular series of bobbins or filling carriers 8 which preferably are supported at their opposite ends for dis charge in turn into the running shuttle. Desirably also I provide a disk 9 preferably fast with the disks 6, 7, for the purpose of guiding or supporting the filling ends 10.

The sleeve 4 is bored or formed large enough to give suflicient clearance between it and the stud 8. At one or more points Serial l lo. 600,064.

within the sleeve 4 I provide what I term an oilless bushing which may be of any suitable material. In the present instance I have indicated two such bushings at 11, 12, and shown as extending into the vertical planes of the two disks 6 and 7. The said bushings 11, 12 are preferably formed of material known upon the market as arguto, but any suitable material performing the same or substantially the same result may be provided. The said bushings 11, 12 are pressed or forced into the sleeve 4, which, if desired, may be slightly recessed annularly therefor as indicated, thus providing chambers 13, 14. The said bushings are forced or positioned in place within the sleeve 4 before the latter has been placed upon the stud 8, andthereafter the said sleeve with its contained oilless bushing or bushings can be readily slid onto thestud 3.

My invention avoids the necessity for oiling the magazine or battery from time to time, and wholly prevents the contact of lubricating oil with the filling. The bushing or bushings will last indefinitely, but if it should become necessary to renew the same, this can be readily done by removing the sleeve 4 and the parts carried thereby from the stud 3. This can readily be accomplished by removing the nut 15 upon the threaded end of the stud 3. The said nut serves not only to hold the sleeve 4 upon the stud 3 with capacity for rotation, but it also serves to retain the bushing 12 in position against the shoulder 14.

The said bushings 11, 12 may be of non metallic or metallic material. When nonmetallic I prefer to employ some suitable wood which has been treated or impregnated with oil, and for this purpose I may employ lignum vitae. If desired, I may employ metallic bushings composed, for example, of alloys, among the ingredients of which may be stellite, which is very hard and has selflubricating properties.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claim.

Claim- A filling replenishing battery or magazine for looms comprising in combination a fixed stud, a sleeve surrounding said stud.

and adapted to support a series i-ofwfilling carriers, an annular internal recess adjacent each end of said sleeve, an oilless bushing removably positioned in each recess intermediate said stud and sleeve and constituting self-lubricatingbearingsfor the latter, and means to retain said bushings in said position While permitting their ready removal, said oilless bushings fonning substantially the'sole bearing surface for said sleeve and whereby damage torthe filling of said carriers from contact therewith of lubricating oil or the like is Wholly prevented and proper lubrication at all times is assured, thus obviating'sliuttle smashes 'esulting from -theisticking 'of'the battery due to faulty or neglected lubrication.

In testimony whereof, I have signed my name to this specification.
